Update: Entertainmentbox.com seems to think this is a well executed April Fool's prank based on looking at how the images are hosted. We can neither confirm nor deny this at this point, but their reasoning seems sound.

Update 2: It turns out Entertainmentbox.com was right. Not only was this a well executed prank, but they were also right about the site being in maintenance mode. Kodi.tv needed to go down for maintenance and a site upgrade, and took the opportunity to have a little April Fool's fun, and at the same time draw attention to "a constant tidal wave of piracy boxes, trademark infringements and erroneous (or outright misleading) news reports." You can read more about it in their news post.

However, despite the "seized-and-offline" gag, there's a serious message here. It is genuinely true that we're facing a constant tidal wave of piracy boxes, trademark infringements and erroneous (or outright misleading) news reports. Hardly a day goes past without the Kodi brand getting dragged into the mud somewhere, and it is a continuous and thankless task to push back on that across this forum, Facebook, Twitter, and the press.
